What is the command to find out how much disk space is being used/remaining?

You can use two commands. The first is to use df - which according to the Ubuntu Manpage:
df - report file system disk space usage
Usage works like such:
df -h
Which should output something like this:
Filesystem Size Used Avail Use% Mounted on
/dev/vzfs 20G 3.5G 16G 18% /
The -h flag provides human readable output (which makes reading of the output - easier).
A second tool is with du which is a slower approach but will give you a better break down of a per directory. Information on that can be found in How to determine where the biggest files/directories on my system are stored?

There are several good command line tools for reporting disk usage. Use the one that's most helpful to you:
df
$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 56G 4.4G 48G 9% /
none 1.5G 256K 1.5G 1% /dev
none 1.5G 472K 1.5G 1% /dev/shm
none 1.5G 400K 1.5G 1% /var/run
none 1.5G 0 1.5G 0% /var/lock
tmpfs 1.5G 596K 1.5G 1% /var/log
tmpfs 1.5G 8.0K 1.5G 1% /var/log/apt
/dev/sdb2 840G 579G 253G 70% /home
df is installed by default.

You can use this command to find out how much space files in your home directory (replace ~/ with / for entire filesystem) and sort by largest files
du -sk ~/* | sort -n
5
Try du -sh <dir>.
For example, du -sh /home/mark will show a summarised usage report in human-readable output for /home/mark.

Or if you prefer graphical gnome-system-monitor

df -h is your best bet (run it in the Terminal).

Note that df -h will show you only remaining space on mounted partitions. Suppose there are NTFS and FAT32 partitions too before running it note that mount all the partitions. If Ubuntu is sole OS on your machine then I don't see any problem with df.
